  • Patent number: 12541746
    Abstract: A method of recycling an integrated circuit (IC) from a printed circuit board (PCB) is provided and includes identifying a target device on a used printed circuit board. The used board is subjected to a screening process including visually inspection and meeting certain criteria. The used printed circuit board is discarded if it is rejected by the screening process. The method further includes preconditioning the used printed circuit board at a temperature greater than 100° C. for a period of time of at least 48 hours, and desoldering the target device from the printed circuit board to isolate the target device. The isolated target device is subjected to visual inspection and functional testing. The isolated target device is then heat treated at a temperature greater than 100° C. for a period of time of at least 12 hours, and subsequently stored in an electrostatic-discharge-protected environment in presence of nitrogen gas.

  • Patent number: 12195923
    Abstract: A method of producing a 3D molded product comprises applying a pulp slurry layer to a porous forming face of a first mold, pressing the pulp slurry layer against the porous forming face of the first mold, while heating the pulp slurry layer and drawing a vacuum through the porous forming face of the first mold, transferring the pulp slurry layer to a porous forming face of a second mold, in a subsequent forming step, pressing the pulp slurry layer against the porous forming face of the second mold, while heating the pulp slurry layer and drawing a vacuum through the porous forming face of the second mold. In the method, a first pressure at the rear side of the forming face of the porous forming face of the first mold is lower than a second pressure at the rear side of the porous forming face of the second mold.
